Saito Hiraga is the love interest of Louise Françoise Le Blanc de La Vallière in the anime The Familiar of Zero.
Saito comes from our world, but was summoned from to Louise's world to be Louise's familiar. At first Louise and Saito did not get along and Louise treated him quite poorly. But as the series progresses, the two eventually come to understand each other and fall in love. Whenever Saito pays any attention to another girl, especially her chest, Louise is quick to punish him. In the anime, Saito's punishment is usually a whipping from Louise's riding crop, a blast from her void explosion spell, or sometimes he is kicked in the crotch by Louise.
